What we checked

Six static checks, weighted by risk. Every result reflects only what could be observed in the published package and repository — never intent.

• Injection surface

  warn25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  tool "get_dart_insider_trades" description: bare 'IMPORTANT:' prose in a description (tag form is high-confidence; prose is warn).

• Supply chain

  pass25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  repository linkage verified

• Credential hygiene

  pass15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  No hardcoded secrets, secret-shaped tool parameters, or leaked keys found. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• Permission scope

  unscannable15% of grade

  Declared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.

  No source files, package.json, or pyproject were fetched; cannot infer capability scope.

• Version behavior

  fail10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  vs prior 0.1.3 (patch bump): tool "import_portfolio" description changed (wording only, no injection pattern); tool "get_portfolio" description changed (wording only, no injection pattern); tool "backtest_portfolio" description changed (wording only, no injection pattern); tool "analyze_factors" description changed (wording only, no injection pattern); tool "analyze_factors" gained input property(ies): neutralize; tool "get_backtest_runs" description changed (wording only, no injection pattern); tool "get_peers" description changed (wording only, no injection pattern); tool "search_dart_company" description changed (wording only, no injection pattern); tool "get_dart_financials" description changed (wording only, no injection pattern); tool "get_dart_financials" gained input property(ies): statement, account_query, account_limit; tool "get_dart_filings" description changed (wording only, no injection pattern); tool "get_dart_major_events" description changed (wording only, no injection pattern); tool "get_dart_insider_trades" description changed (wording only, no injection pattern); tool "search_edgar_company" description changed (wording only, no injection pattern); tool "get_edgar_financials" description changed (wording only, no injection pattern); tool "get_edgar_filings" description changed (wording only, no injection pattern); tool "get_edgar_insider_trades" description changed (wording only, no injection pattern); tool "search_fred_series" description changed (wording only, no injection pattern); tool "get_fred_series" description changed (wording only, no injection pattern); tool "get_fred_snapshot" description changed (wording only, no injection pattern); tool "get_crypto_ticker" description changed (wording only, no injection pattern); tool "get_crypto_ohlcv" description changed (wording only, no injection pattern); tool "compare_crypto_exchanges" description changed (wording only, no injection pattern); tool "get_db_schema" description changed (wording only, no injection pattern); tool "query_db" description changed (wording only, no injection pattern); tool "screen_companies" description changed (wording only, no injection pattern); tool "get_stock_prices" description changed (wording only, no injection pattern); tool "screen_etfs" description changed (wording only, no injection pattern); tool "get_technicals" description changed (wording only, no injection pattern); tool "screen_technical" description changed (wording only, no injection pattern); tool "get_valuation" description changed (wording only, no injection pattern); tool "get_valuation" gained input property(ies): per_multiples, pbr_multiples; tool "screen_minervini" description changed (wording only, no injection pattern); tool "screen_canslim" description changed (wording only, no injection pattern); tool "screen_kell" description changed (wording only, no injection pattern); tool "screen_schwartz" description changed (wording only, no injection pattern); new tool "get_watchlist" touches a sensitive surface (email/exec/net/fs); new tool "manage_watchlist" appeared; new tool "delete_backtest_run" touches a sensitive surface (email/exec/net/fs); new tool "get_dart_document" appeared; new tool "get_tw_insider_transfers" touches a sensitive surface (email/exec/net/fs).

• Transport config

  pass10% of grade

  Remote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.

  remote endpoint "https://mcp.gronox.kr/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
